Answer :
Answer:
36 cubes
Step-by-step explanation:
A rectangula prism with a volume of 4 cubic units is filled with cubes with side lenghts of 1/3 units.
Volume of cubes = (side length)³
Volume = (1/3)³
= 1/9 cubic units
Therefore, the number of 1/3 unit cubes it takes to fill the prism is calculated as:
= 4 cubic units ÷ 1/9 cubic units
= 4 × 9/1
= 36 cubes
